PHoNoGRArH-s'ron Specification of Letters Patent.

Patented July 22, 1919.

Application filed December 9, 1918. Serial No. 265,894.

To all whom it may concern:

Be it known that I, RICHARD KiinnsTLnR, a citizen ofithe United States,and a resident'of the city of Chicago, county of Cook, and State ofIllinois, have invented certain new and useful Improvements in Phonopsof which the following is a specification. g v

My invention relates to improvements in phonograph stops, and has forits object the production of mechanism of this character which will beof "durable and economical construction, and through the medi un. ofwhich :a phonograph will be automatically stopped upon opening of thecabinet cover.

Other objects willappear hereinafter.

The invention consists in the combinations and arrangements of partshereinafterdescribed and claimed.

The invention will be best understood by reference to the accompanyingdrawings forming a part of this specification, and in which, I y IFigurel, is a top plan view of a phonograph embodying the invention, afragment only of the phonograph cover being shown,

Fig. 2, a vertical section through the upperportion of the phonograph,

y. Figs. 3 and 4, views similar toFigs. 1-. and 2,respectively, showinga slightly modified form of construcition, andf Fi .,5 atop an view 0aslightl modifiedf orinoi brgke. y y

The -mechanism embodying the invention herein is designed foruse inconnection with a conventionalphonograph, such as embodies the cabinet10 and rotary record table or support 11 which is carried by a shaft 12,the record 13 being adapted .to loosely rest upon thetablewll, as, seenin the several views. Such form of phonograph alsocomprises a swinginglymounted tone 'arm'lt, thefront end portion 15 ofwhich carries a stylus16 being pivoted 17 to swing vertically, as will be readily understood,The usual brake lever 18 .is shown, whereby operation of the'phonographis usually controlled, this, brake, with the present construction,being-however, only employed to permanently arrest thephonograph or whenthe phonograph is tobe stopped for some considerable periodg Otherwise,the stop 18 is moved to released or i i-operative position. At thetop ofthe phonograph cabinet is provide th .le i alflcorer- ,l9,,, .ia .e a 20permit at upward swinging" thereof.

The mechanism forming the subject matter of thisapplication comprises,as shown in Figs. 1 arid 2, a brake 20 which pivoted at 21 so as topermit of the shoe 22 thereof engaging with the periphery of the recordtable, as will be readily understood. A helical tension spring 23 coepeites with said brake 20 to normally hold the same in released orinoperative position. Connected with said brake 20 is an operating cord24., which passes through a "guide eye 25 and being then connected withthe tone arm 14 of the phonograph. The arrangement is such, that whensaid tone. arm isfin initial or starting position, the brake 20 will beheld thereby in operative position or in engagement with the recordtable 11 to arrest movement ofthe latter. V

The movable end 15 of said tone arm is connected by means of a cord 26with an eye 27 carried by the cover 19, The arrangement is such, that inthe opening movement of said cover, saidtone arm section 15 will beraised from engagement with the record, as clearly seen in Fig. 2.Further, the arrangement is such, that, in the rendition of a record,when the stylus is positioned at the inner end of the tone groove of therecord, the cord 26 will be positioned below the centerof oscillation ofthe tone arm 14, as seen in Fig. l, or in such a position that, uponraising of the cover, not only will the tone arm section 15 be liftedfrom the record, but the tendency of the upon said cord 26 will be suchas to effect automatically the return swinging of tone armll to itsinitialposition. Hence, with this arrangement, it will be seen that uponrendition of a record,

when the cover is raised to open position, the tone arm will beautomatically lifted from engagement with the record, swung back toinitial position, and in the latter movementcallse application of stopor brake 20 toefi'eot ai'itoinatic stopping of the phonoe ap In the formof construction shown in Figs. 3 and 4, a brake 20 is provided similarto the brake 20, but arranged for engagement with the inner side-of theperipheral flange of the record table or support. In this form, however,the brake operating cord 28 passes through guide eyes 29 .and.,i sconnected with;the eye .27 with which the cord 26 connected with thetone section 15 e -W. h t is.. .a eegtn h th efeat,- it will be seenthat the opening move ment of the cover 19 performs directly the doublefunction of lifting the tone arm member 15 from engagement with therecord, and setting the brake 20. In this form, also, a cord 30 connectsthe tone arm 14 with the cord 28 so as to positively insure returnswinging of the tone arm in the opening movement of the cover.

The cord 26 and eye 27 are so positioned, relative to the pivotal axisof the tone arm let, that when said tone army is at its inner terminalmovement, as illustrated in dotted lines in Figs. 1 and 3, the cord 26will have passed beyond the said axis of said tone arm so that any pullupon said cord will have a tendency to hold the tone arm in thisposition. This is of special advantage in that it permits of insertionor removal of a needle without fear of the tone arm being swung off tothe side or toward initial position during the operation. Said cord andeye are,

however, so positioned that when the needle has reached the innerterminal of the tone groove of the record, which is theintermediateposition of the tone arm shown in clotted lines in Figs. 1 and 3, saidcord 26 will, as has before been pointed out, be positioned at theopposite side of the pivotal aXis of the tone arm to insure automaticreturn thereof to initial position upon lifting of'the cover 19. Thefeature just described applies only to the construction seen in Fig. 1,inasmuch as in the construction shown in Fig. 3 the tone arm isconnected directly with the cover 19 so as to effect positive swingingof said tone arm to initial position upon lifting of the cover. In theconstruction seen in Fig. 1, the tone arm is not connected in thismanner.

i If desired, the brake employed may be of the construction seen in Fig.5, in which the body thereof is formed of a wooden block 31 adapted tobe pivotally secured at 32, said block carrying the shoe 33 securedthereto by a staple 34.

While I have illustrated and described the preferred forms ofconstruction for carrying my invention into effect, these are capable ofvariation and modification without departing from the spirit of theinvention. 1, therefore, do not wish to be limited to the precisedetails of construction set forth, but

. desire to avail myself of such variations and modifications as comewithin the scope of the appended claims. 2

Having described my invention, what I claim as new and desire to secureby Letters Patent is 1. The combination with a phonograph having arotary record support; a pivotally mounted tone arm; a movable cover, ofmeans for automatlcally stopping operation 'of the phonograph uponrendition of a record, comprising an operative connection between saidtone arm and said cover whereby,

upon opening movement of said cover, said arm will be raised fromengagement with the record; a brake cooperating with said recordsupport; and means for applying said brake simultaneously with themovement of said tone arm from engagement with the record, substantiallyas described.

2. The combination with a phonograph having a rotary record support; apivotally mounted tone arm; a movable cover, of means for automaticallystopping operation of the phonograph upon rendition of a record,comprising an operative connection between said tone arm and said coverwhereby, upon opening movement of said cover, said arm will be raisedfrom engagement with the record; a normally inopcratively positionedbrake adapted for engagement with the record support; and means forapplying said brake simultaneously with the movement of said tone arm.from engagement with the record, substantially as described.

3. The combination with a phonograph having a rotary record support; apivotally mounted tone arm; a movable cover, of means for automaticallystopping operation of the phonograph upon rendition of a record,comprising an operative connection between said tone arm and said coverwhereby, upon opening movement of said cover, said arm will be raisedfrom engagement with the record; a normally inoperatively positionedspring-held brake cooperating with said record support; and means forapplying said brake simultaneously with the movement of said tone armfrom engagement with the record, substantially as described.
